Abstract: 217,267. Richardson, R. P., Cole, T. N., and Ward, G. L. Feb. 6,1923. Regulating Switches.-The contact-plates of a regulating switch are mounted on the base on which an inductance is wound and the controlling stem is mounted centrally in the base; the device is secured to the cover-plate of a wireless receiving set by means requiring only one perforation in the cover-plate. In the apparatus shown in Fig. 1, the inductance comprises a coil 1 wound on an insulating former 2 closed at one end by a plate 3 and at the other by a plate 4 carrying contact studs 5 connected to tappings on the coil. A switch arm 10 mounted on a. central stem 7 which passes through a threaded bush 11 screwed into the plate 3. The inductance may be mounted on the cover-plate of a wireless receiving set by passing the bush 11 through a perforation therein and securing it together with a graduated disc 12 by a nut. A knob 8 and pointer 9 are mounted on the spindle 7. In a modification the 'former 2 is grooved to receive the wire, and the bush 11 and its nut are replaced by a flanged bush which is inserted through the hole in the cover-plate and screwed to the former. A variable inductance of the above kind may be provided with means for varying its coupling with a second inductance of fixed value mounted on the same base, as shown in Fig. 4. A multi-layer coil 24 has tappings connected to contact studs 25 on an insulating plate 26, the studs being engaged by a switch arm 27 mounted on a hollow stem 28. The second inductance 35 is mounted on a former 34 having a threaded central aperture engaging a threaded rod 33 secured to a stem 31 passing through the stem 28. The former 34 is prevented from rotating by guides 36. The unit is secured to the cover-plate of the set by a ranged and threaded bush 21. A knob 29 and pointer 30 are secured to the stem 28, and a knob 32 to the stem 31. In a modification, a tapped cylindrical inductance is caused to slide over a cylindrical inductance of fixed value by axial motion of the switch arm stem. Pins on the sliding inductance engage holes in the fixed one to prevent rotation.

Filed: 1939-02-03
Abstract: 524,698. Knitting. FOISTER & SONS, Ltd., A., and FOISTER, J. E. Feb. 3, 1939, No. 3643. [Class 74 (ii)] Interlock fabric is vertically striped as the result of the absence of needle wales from one or each web or face. In the form shown, the needle wale d which would normally be knitted of the fabric of one web 3 is omitted so that a stripe of the width of two wales and of the colour of the material of the other web 4 is obtained. At wale e, the needle wale is omitted to form a stripe of the colour of the material of the web 3. The corresponding needle wales in the two webs or faces can be omitted so that stripes of one material on one face are backed by stripes of the other material on the other face. The striping effects so formed may be combined with other patterns or fancy effects such as horizontal striping or tuck stitch effects. The fabric may be a 1 x 1 or broader rib formation. The fabric may be made on a flat or straight bar rib machine, or upon a circular machine, needles being omitted from the needle bed where it is desired to omit the needle wales in the fabric.

Abstract: 1,113,822. Semi-conductor devices. SIEMENS-SCHUCKERTWERKE A.G. 27 Jan., 1966 [30 Jan., 1965], No. 3817/66. Heading H1K. Figs. 1 and 2 represent diodes the silicon bodies of which are provided with alloyed aluminium and gold-antimony contacts. A molybdenum disc is directly heat bonded to the aluminium contact and a further molybdenum disc, the inner surface of which may be silver plated, is heat bonded to the gold contact through an intervening silver foil. In the diode of Fig. 1 (not shown), stepped silver cover plates (6, 7) are hard soldered to each of two ceramic annuli (2, 3) having hard-soldered rings of iron-cobalt-nickel alloy attached thereto. The two rings (4, 5) are welded together. In the diode of Fig. 2 a single ceramic annulus 28 is hard soldered to iron-cobalt-nickel annuli 26, 27 and a third similar annulus 25 welded to annulus 27. Projections 30 on the alloy annuli ensure that clearance is left between the main plane of the annulus and the ceramic body. The stepped silver covers 21, 22 are hard soldered to the alloy rings before the housing is assembled. Bolts 32, 33 hard soldered to the alloy rings 25, 26 are used to secure insulating rings 34, 35 of P.T.F.E. or hard paper to the housing, an aperture being left in the upper ring to receive the evacuating stub 31. The external mountings 36, 37 serving as heat sinks are shaped to allow pressure to be applied to the silver cover plates and to ensure accurate alignment of the housing with the mountings. The housing of Fig. 3 (not shown) is generally similar to that of Fig. 2 but is adapted to take a thyristor whose third electrode is set within a recess in the molybdenum plate (42). Contact to the third electrode is made by a spring contact (44) connected by a silver wire (57) to an iron-cobalt-nickel pin (56) led through an insulating bushing (55) from the housing. A frame (43), as described in 1,070,484 is used to hold the semi-conductor element during and subsequent to assembly of the housing. The evacuating tube (66) mounted in the stepped iron-nickel-cobalt ring (49) extends to an aperture in the frame to prevent it and the semi-conductor element from rotating within the housing. Frames similar to frame (43) may be used in the housings of the devices of Figs. 1 and 2.

Abstract: 1502801 Lasers JERSEY NUCLEARAVCO ISOTOPES Inc 30 Jan 1975 [30 Jan 1974] 4121/75 Heading H1C [Also in Division G2] In a laser system in which a plurality of sequentially pulsed lasers 44, Fig. 4, have their outputs directed into a generally common path by a synchronized rotating optical structure which may comprise a prism 46 or an array of angled mirrors 74, Fig. 5, the dynamic angular variation of the pulse radiation outputs produced in the common path by movement of the rotating structure during each pulse period is minimized by a compensating optical system. In the Fig. 4 arrangement compensation is effected by the combination of a so-called "K" mirror 56 and an array of angled mirrors 60, these optical components being rotated in opposite directions with the "K" mirror driven at one half of the angular velocity w of the prism 46. A synchronizer 50 co-ordinates the respective drive motors 48, 54, 62 and the pulses from lasers 44. The combination of a plane mirror and a spaced V-shaped mirror form the "K" mirror. Alternatively a dove, reversion or Pechan prism may be used. The Fig. 5 arrangement has a compensating structure consisting of parallel reflecting surfaces 78, 80 of a rotated rhombic prism 76, the prism being driven in synchronism with the mirror array 74 so as to be aligned with each operative laser in turn and to direct that laser output into a common path 82. In a modification, Fig. 6 (not shown), the beam 75 between the array and the prism is arranged to converge towards the rotation axis, the reflecting surfaces 78, 80 of the shorter prism then required being such as to receive this radiation and transmit it along the common path. Further compensation is obtainable by including an angularly displaced rotated optical flat in the radiation path, Fig. 9 (not shown). A plurality of such laser systems may have their combined outputs themselves combined as shown in Fig. 7, in which each system comprises plural lasers 104 and a synchronized rotating optical combiner 106, and the common path outputs are combined together by a rotating optical combiner 108. As an alternative lasers 116, Fig. 8, having high repetition rate output pulses have their outputs decombined at 126 into separate paths 120, the separate outputs of all the lasers being then combined together into a single common path by a combiner 122.

Title: Improvements in or relating to pneumatic tire deflation warning devices
IPC: B60C23/04
Filed: 1964-01-31
Abstract: 1,008,233. Tyre-deflation warning devices. J. C. O'NEAL. Jan. 31, 1964 [Feb. I, 1963], No. 4338/64. Heading B7C. A deflation warning device for connection to the valve stem 12 of a pneumatic tyre comprises a housing 10 in which a transverse flexible diaphragm 27 is detachably secured by a sleeve 28, the diaphragm being urged towards a sharpened projection 21 by a spring 37 with a force to move the diaphragm into contact with the projection on a predetermined reduction in pressure in the tyre and so rupture the diaphragm and allow air to escape, warning means being operated by the escaping air. Before inflation of the tyre (Fig. 1) the diaphragm is held away from the projection 21 by a projection 38 in the sleeve engaging a recess 39 in a member 34 around which the spring is mounted. Inflation of the tyre through a valve 14 causes the diaphragm and spring to assume the position shown in Fig. 3. A friction-mounted cap 46 protects the free end of the housing. Upon a predetermined reduction of pressure in the tyre, the diaphragm is urged by the spring towards the projection 21 and is ruptured (Fig. 5), air then escaping through a passage 41 in the member 34, blowing off the cap 46 and operating a whistle 42 or means (not shown) dispensing a powder or liquid. Escape of air from the device after rupture of the diaphragm may be retarded by engaging a projection 43 on the housing in a recess 44 in the member 34, thus urging the member 34 against the projection 21. The device may be used again by unscrewing the sleeve 28 and inserting a fresh diaphragm.
